Ancient Reptiles
The landscape of the biological world more than 200 million years ago is shown in the hall of Ancient Reptiles. The crossopterygians, Ichthyostega, gymnophionan amphibians and Dimetrodon are selected as representatives to demonstrate the complexity of vertebrate development transitioning from water to land. In the center of the hall displayed lifelike dinosaur skeletons including Lufengosaurus huenei known as the first dinosaur discovered by a Chinese scientist, the 26-meter-long Mamenchisaurus jingyanensis, and the Tuojiangosaurus multispinus with sword-like back plates, the majestic Yangchuanosaurus, the soaring pterosaurs, and the ichthyosaurs that dominated the ocean.
